SPECIFICATION forming part of Letters Patent No. 288,874, dated November20, 1883.

Application filed September 26, 1883. (No modelfl' Patented in FranceSeptember 24, 1881, No. 145,007; in England January 13, 18S-2, No. IE6;in Austria-Hungary January 16, 1382, No. 2,996 and No. 12,981 in SpainJanuary 24, 1882, No. 2,652,- in Denmark January 30, 1852, No. 335 3 inNorway February 2, 1882, and in Sweden February 14, 1882.

To all' whom t 11mg/ concern.-

Be it known that l, Gnonens SEIBEL, of Cransac, France, have invented anew and useful Improvement inCoke-Furnaces, (for which l have obtainedPatent in France on September 24, 1881, No. 145,007 5 in Austria-HungaryNo. 2,996, and No. 12, 981, on January 16, 1882; in England, No. 186, onJanuary 13, 1882; in Spain, No. 2,652, on January 24, 1882; in Denniark,No. 335, on January 30, 1882 5 in Sweden on February 14, 1882, and inNorway on February 2, 1882,) of which the following is a specifica-tion.

My invention relates to the manufacture of coke from coal, especiallyfrom bituminous coal, and is based on the fact, observed by me, that thehydrocarbon gases produced by the distillation of coal, and passing at ahigh temperature through a mass of coal which is being converted intocoke, yield a portion of their carbon to the spongy material throughwhich they are passing, and that the quantity of carbon thus given offincreases with the thickness of the coal stratum through which the saidgases are filtered.

My invention consists of a peculiar combination of ues and tuyeres in acoke-oven, which dispenses entirely with a grate, land is heated by thegas arising from the distillation of the coal, and will be fully setforth in the description below,aud pointed out in the claims.

In the accompanying drawings, which represent a series of furnacesembodying my invention, Figure 1 is a vertical section across thecokechanibers, ta-ken at different parts of their length, the planes ofsection being indicated in Fig. 3, and designated with l Il lll IV V VI.Fig. 2 is a longitudinal section of a coke-chamber, taken along theplane H H of Fig. 1. Fig. 3 is a vert-ical section along the plane L Lof Fig. 1; Fig. 4., ahorizontal section of a furnace along the plane M Mof Fig. 3; Fig. 5, a section along the plane N N', and

Fig. 6 a sect-ion along line It Il. Fig. 7 is a,`

front view of a furnace, the line x y indicating the sole of thecoke-chambers.

The coke-chamber A, covered by a vault, is about 1.98 meters high, 0.700meters wide, and six meters long. 7`With these dimensions the quantityof coal in one chamber is about live thousand kilograms. It should becharged with coal to a height of at least 1.700 meters.

'The partitions which separate the furnaces are provided with threehorizontal flues, B, B', and B2, communicating with two fines, C, underthe sole ofthe furnace, leading through a vertical flue, D, to a largecollecting-gallery, E. This gallery passes along the front of thefurnaces at a lower level than the sole, and carries the gases ofcombustion from all furnaces to a chimney. Before arriving there the hotgases may be utilized for heating boilers.'

In order to obtain the desired result-that is to say, the deposit of apart of the carbon contained in the gaseous products of distilla tion inthe pores of the coke which is in course of formationit is necessary tocommence the carbonization of coal at the top. For this purpose gas isintroduced at one end of the upper ilues, B B, through suitabletuyeres,F F, and ignited, the air necessary to aid combustion beingadmitted through the center of said tuyeres and controlled as to amountby suitable dampers. (See Fig. 3.)

By this construction the grate used in other coke-furnaces heated by gasis dispensed with. The gases of combustion formed in the upper ue passdownward through the central and lower iiue to the sole of the furnace,and from there to the chimney, heating during their passage the wallsand base of the furnace.

After the chamber A has been charged with coal, its walls are nearlycold; but the gas ignited in the upper ilue heats rapidly the top of thefurnace, where the distillation of coal begins. The tempera-ture soonrises also in the lower part of the furnace and causes the distillationto extend to the whole mass of coal. The gases formed in the lower partgive oft' a part of their carbon to the material in the upper part,whereby the production of coke in this furnace is considerablyincreased. The gas produced in the chamber A is drawn out at P by anaspirator, which presses the gas directly into the furnace after it hasbeen puriiied from tar and ammoniacal water. From the delivery-pipe llead a branch pipe to a gasholder. As soon as an abundance of gas isproduced in the furnace the pipe leading to the latter is closed' forsome time and the gas I conducted to the gas-holder, from where it maywhich case a greater supply of gas is required for rapidly heating thefurnace.

Instead of three superposed flu'es, as shown j in the drawings, two ormore than three may 'be used.

What I claim is- I. In a coke-oven, the combination of the iiues B,having` the tuyeres F,With the flues B B2, provided with thesupplementary tuyeres which divides said flues B B2, the partitiondeiiecting the ame equally into each to rapidly heat the lower part ofthe oven, as set forth.

2. In a coke-oven, the combination of the iiues B, having the tuyeres F,and the flues B B, provided with the supplementary tuyeres G, enteringdirectlyopposite to the partition which divides them, with the iiues C Dand the gas-reservoir E, as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.
